Data Characteristics
Medical insurance access policy data originates primarily from policy documents, drug catalogs, treatment scope, and payment standards published by national and local medical insurance bureaus. This data updates frequently, typically quarterly or annually, with ad-hoc updates for significant policy changes. Document formats vary, including official PDF files, Excel spreadsheets for drug or treatment lists, and structured data from online platforms. Drug catalogs include generic names, trade names, dosages, specifications, medical insurance payment categories, and restricted payment scopes. Treatment items include codes, names, prices, and payment ratios. Units are commonly "yuan," "percentage," or "mg/tablet."
Constraints Imposed by These Characteristics on "HTTP Interface and External Systems"
The diverse sources of medical insurance access policy data require the HTTP interface to have robust file parsing capabilities, especially for structured extraction from PDF and Excel files. High update frequency means the system must support scheduled tasks or Webhook mechanisms to pull the latest policy changes promptly. Complex document structures, particularly descriptive texts like restricted payment scopes, demand advanced natural language processing and semantic understanding, influencing knowledge base segmentation strategies. Standardized handling of fields and units is critical for accurate question answering; the interface must normalize units during data ingestion. Policy sensitivity also necessitates strong authentication and data transmission security for the interface, ensuring accurate policy information delivery.
Configuration Settings
| Configuration Item | Suggested Value | Rationale |
|---|---|---|
maxContext | 3000 Tokens | Medical insurance policy documents are often long, requiring a larger context window to understand policy details. |
PARSE_FILE_TIMEOUT_SECONDS | 600 seconds | Parsing large PDF or Excel files can be time-consuming; this allows sufficient time to prevent timeouts. |
Chunk size | 800 characters | Policy clauses typically contain multiple conditions and explanations; this length helps maintain semantic completeness. |
Similarity threshold | 0.75 | Medical insurance policy Q&A demands high accuracy; increasing the threshold reduces irrelevant recalls. |
Rerank result count | Top 5 entries | Ensures core policy terms are displayed first, improving efficiency in obtaining key information. |
HTTP_REQUEST_TIMEOUT_SECONDS | 120 seconds | External medical insurance data sources may experience network latency; extending the timeout prevents request interruptions. |
Common Mistakes
- An external API call returns empty data, possibly due to external system authentication failure or missing request parameters.
- After a knowledge base update, application conversations still return old policy information because the interface linking the knowledge base and the application did not trigger or was incorrectly configured.
- During medical insurance policy file parsing, some critical fields (e.g., restricted payment scope) are not correctly extracted because file parsing rules do not fully cover all document structures or OCR recognition accuracy is insufficient.
How to Verify Configuration
- Upload a recent medical insurance policy PDF file via the HTTP interface. Confirm file parsing status is normal and the file content is retrievable in the knowledge base.
- Simulate a medical insurance access-related query via API. Observe if the returned results contain the expected policy terms and verify their accuracy.
- Check external system synchronization interface logs. Confirm data fetching tasks execute at the expected frequency without connection errors or data parsing exceptions.
- Configure a Webhook for medical insurance policy updates. After triggering, verify that the knowledge base content updates promptly.
